Snow Flakes And Fates:
What Hope Is There For Alpine Winter Tourism?

Abstract
The rapid development of Alpine winter tourism and related infrastructures
during the last century raises the question of development prospects against the
background of climate change and sustainability. Today, amongst other
macroscale forcings, snow is considered a precondition for winter tourism. The
aim of this study is to investigate past climate change for four communities in
Tyrol in relation to the number of overnight stays, and to compare the variability
of the current climate with the bandwidth of future scenarios. This is done by
analysing i) trends of air temperature, humidity and snow and ii) the statistical
correlation of these parameters with the number of overnight stays. The height
and duration of natural snow cover show high interannual variability. As a
technical response, snow production has developed rapidly. Applying a
Mann-Kendall test to the wet-bulb temperatures recorded at three Tyrolean
climate stations reveals that the time frames when snow production is possible
have changed most at medium elevations, but have so far not exceeded a few
days at the beginning and the end of the winter season. In contrast to summer
mean temperatures, winter mean temperatures have not changed significantly
during the last 3 decades, and the range of interannual variability was about three
times that of the most extreme temperature change calculated for future climate
scenarios. Therefore it is very likely that the average future winter climate means
will be within the range of the past century’s records, and snow cover and
temperature changes are minor macroscale forcings, so they are not factors that
would delimit the future developments of Alpine winter tourism.
Keywords
climate change, winter tourism, snow production, ski tourism, snow
cover.
